HENRY VOLKENING, OF NEW YORK, N. Y.

POLISHING-MACHINE.

Specification of Letters Patent No. 11,797, dated October 101854.

To all 'whom t may concern:

Be it known that I, HENRY VOLKENING, of New York City, in the county and State of New York, have invented a new and I1nproved Sandpaper and Pumice-Stone Polishing Machine; and I do hereby declare that the following is a full and eXact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in the application of an elastic substance, such as woolen blankets or india rubber between the sandpaper and wood, or if the machine is made of metal, between the sandpaper and metal, and if pumice stone is used for polishing purposes, and which in that case is applied on leather, then the elastic substance is placed between the leather and the body upon which the same is stretched.

In the following drawing Figure l reprew sents an longitudinal elevation and Fig. 2 a section of a rotary polishing machine.

(A) is a cylinder made of wood or metal fast on a shaft (B) running in bearings on the frame (C). On the end of the shaft (B) a pulley (D) is attached to turn the same by power or a handle may be fastened instead, to turn the cylinder by hand.

A small groove is made lengthwise in the cylinder 1n which a bar is fitted. Round this cylinder woolen blankets (E) or india rubber about from one-quarter of an inch to one inch or more in thickness are placed in such a manner that the ends can be turned down in the groove and the sandpaper H then placed outside this elast-ic substance and the ends likewise turned into the groove, where the whole is firmly secured through the bar, o, which is fastened with screws to the cylinder A.

The advantage of this machine is principally for polishing mouldings or uneven surfaces, but plain surfaces can likewise be polished with the same.

I do not claim any particular kind or arrangement of polishing machines, but

I claimi The application of an elastic substance or cushion between the polishing material and Vthe body to which the same is attached.

HENRY VOLKENING.
